BAXTER M. ASLAKSON, OF SALEM, OHIO.

' MEANS FOR DRIVING AIR AND GAS PUMPS.

Application filed June 18, 1908.

To all whom it may concern Be it known that I, BAXTER M. ASLAKSON, acitizen of the United States, and residing at Salem, Columbiana county,Ohio, have invented certain new and useful Improvements in Means forDriving Air and Gas Pumps, of which the following is a specification.

My invention relates to gas engines and particularly to means fordriving a gas and air pump through the instrumentality of a flexibleconnection.

The object of my invention is to provide a flexible means to be locatedbetween the main crank of the engine and an auxiliary crank and to drivethe latter crank by the former through the flexible means, and toprovide a novel and eflicient construction of the latter.

Referring to the drawings which form a part of thisspecification,--Figure 1, is a plan view of a portion of a gas engine inwhich is disclosed my arrangement of the cranks and flexible means. Fig.2, is a cross sectional view through the bearing of the 'main shaft ofthe engine and the auxiliary shaft bearings, disclosing the two cranksand the flexible means located between them. Fig. 3, is a side view ofthe flexible driving means. Fig. 4:, is a sectional plan view of theflexible driving means. Fig. 5, is a cross sectional view through theauxiliary shaft and disclosing the lay shaft of the engine and means fordriving same.

A, indicates the frame of a gas engine having a main bearing B and mainshaft C, and

mounted on one end of said shaft is the main crank D, which is providedwith the usual crank pin D.

j E, indicates the main connecting-rod which is connected to the crankpin D in the usual manner.

F, indicates an auxiliary crank which is mounted on a short shaft G,which shaft is connected to and drives a third crank H, which crank isthe driving crank for operating the gas and air pump of the engine.

G indicates a short shaft which is also connected to the crank H, asshown, and the axis of the shafts G and G are in line with the axis ofthe main shaft C. Now since the main shaft C and the auxiliary shafts Gand G are supported in separate bearings and subject to a different rateof wear, the axis of the two shafts may get out of alinement with eachother and thus subject the Specification of Letters Patent.

respective parts to undue strain and friction, which will cause thebearings to overheat and cause trouble. To overcome this difficulty, Ihave provided a flexible connection comprising a link I, which isconstructed in such a manner as to provide means for in creasing ordecreasing the length between its boxes J and J, each of which is madein two halves which are duplicates of each other, and are provided withflanges, each .containing a hole through which threaded bolts j and jare passed and secured therein by means of nuts KK, etc., which screwthereon and abut the opposite sides of said boxes as shown to hold themapart a proper distance from center to center, as will be readilyunderstood. The boxes J and J are each provided with a ball shapedsurface which fits over the globe shaped ends of the crank-pins L and Lrespectively, to form a flexible joint which will permit of a certainamount of lateral movement between the respective cranks to which theyare connected. The ball shaped ends of the crank-pins may be formed of aseparate piece of metal as shown at L and held to the crank by a bolt M,as indicated. The crank-pin D is arranged to travel in advance of thecrank-pin of crank F, to form a drag-crank connection, the pin L beingconnected to and projecting from the main crank-pin D, and the crank-pinL being connected to the crank F, as indicated.

N, indicates the connecting rod by means of which the pumps are driven,and O indicates the lay shaft, which is driven by a worm gear P, whichin turn is driven by gear Q, which is mounted on the shaft G, as shown.The lay shaft drives the governor R and operates the valves of theengine.

S, indicates an eccentric which drives a valve gear to operate thevalves of the air and gas pump.

By the use of this flexible connection, oversurfaces, and a linkoperatively connecting the crank pins with the ball surfaces havingboxes provided with ball socket-s.

2. The combination of relatively fixed bearings spaced apart, shaftsrespectively journaled in the said bearings, a driving crank attached toone of the shafts and having a crank pin, a crank attached to the othershaft having a crank pin, a crank pin attached to the crank pin of thedriving crank, the crank pin of the second named crank and the crank pinattached to the crank pin of the driving crank having ball surfaces, alink operatively connecting the crank pins with the ball surfaces havingboxes provided with ball sockets, and means for adjusting the boxes tocorrespond with the distance between said crank pins to which they arerespectively connected.

In testimony whereof, I have signed my name to this specification in thepresence of "two subscribing witnesses, this tenth day of January, 1908.
